View of the outside of gym.

Great equipment with great coaches. Never have to wait on a rack. The coaches tell you exactly what to do and the community of athletes is fun to be around l.

Eric S.

Brayden and the team of trainers/ coaches are the finest group of people you will ever meet! They tough me so much about strength and training. Let's go

Wednesday morning 9am training session.
Jason M.

After hurting myself for years doing Crossfit, I decided it was time to hit the reset button and start working on form and technique over speed and volume. I couldn't be happier. Grant and his coaches are all credentialed experts, masters of movement and excellent at making cue suggestions on-the-fly that help the athlete make minor corrections for maximum results. Another plus, the small gym size means 1:1 coaching of every rep for every athlete in the gym. It's like having a personal trainer three times a week, for half the price. Highly recommended.

My excitement after successfully doing my final deadlift at the gym's 2022 Turkey Pull.
Gail E.

If Grant & Breyden had told me that after only 9 months of working with The Strength Co I would be able to go from not knowing how to do a deadlift to comfortably pulling 210 lbs I would not have believed them. I am 65 years old and have never considered myself athletic. The program works. And the support I have gotten has been terrific. Last week they sponsored a very fun "Turkey Pull" where folks challenged themselves doing 3 rounds of deadlifts. I wonder if next year we will do "Turkey Squats". If you live in Orange County & you want to Powerlift, this is the gym for you.

Deadlifting 240 pounds. Bet you can do this too.

Trying to call so many times but always ended up in voice mail. There is no infos on your website about the membership. So how could I get more information how to join?

The gym doesn't always answer the phone when they are training. Try emailing the owner (Grant) directly, he is really good about getting back to everyone quickly.…

Update: 7/23/26…read more After a year at this gym. I've spoken to some of the team member - especially a person name Javier. I inform him my concerns, thoughts and recommendation. This gentlemen listen to me closely and heard what I said. The gym updated paper towels and chemicals to wipes. I see staff and cleaning crew helping out by keeping the gym clean. Sweat is being wiped down from the machine. Javier has updated me that they are looking to post signs as a respectful reminder for folks. I want to upgrade my 3 star to 5. Thank you for listening to me and taking initiate. Appreciate it. I will be keeping my membership on going with my wife.

I started out really loving this gym, it's always very clean and they have a wide variety of…read moreequipment, and it's a great price for everything they offer. However, this gym is very busy and with people who have questionable gym etiquette. You'll often see guys working out with their shirts off, saving 2 machines at once with their gym bag on one, and on their phone on the other, while flexing into their selfie sticks. It wouldn't be a big deal if this gym wasn't constantly busy, but it is. It doesn't matter what time of day you come, it's always full. Today, there was a hot pink Lamborghini parked in the handicap spot directly in front of the door. Really? I said something to the front desk, not to be a "Karen," but because there are indeed real disabled members that work out here. Oh... and it's uhhhh... illegal and just plain disrespectful. He shrugged his shoulders, and totally blew me off. Curl management could really improve on setting some etiquette rules for the members it's getting really out of hand.

The Holy Spirit led me to leave this review today after being a member since December 2025…read more I praise God for how He is using Mark and Kat to help people become more physically healthy while also introducing them to what matters most--Jesus Christ. Their commitment to honoring the Lord through their business is evident. The facility is always well-stocked, the equipment is organized (unlike many public gyms), and everything is consistently clean and well maintained. It's a welcoming environment where excellence and care are clearly a priority. I truly believe the Lord will continue to bless Mark and Kat, both in their business and in their family, because of their faithfulness and obedience to Him. The Scripture that comes to mind is Psalm 37:5: "Commit everything you do to the Lord. Trust Him, and He will help you." May the Lord Jesus Christ continue to increase your influence, bless your work, and grant you favor as you faithfully walk in obedience to Him.

Every penny is invested in your health , what you pay is what you get, and let me tell you that I've never been this happy with a gym. I also love that they are not afraid to spread the gospel and put Jesus first, always.

He truly cares about your well-being and motivates you to do better each day.

I've been coming here since February, and joining this gym has honestly been one of the best…read moredecisions I've made this year. At first, I was really intimidated. I had only ever gone to places like 24 Hour Fitness, so walking into a more serious training gym was completely out of my comfort zone. But from day one, everyone made me feel so welcome. The front desk staff is always friendly, and they even have a little coffee bar in the mornings, which is such a nice touch. I've been training with AJ, and I can't recommend him enough. Coming from someone who knew almost nothing about gym equipment or strength training (I was mainly a Pilates girl), he made everything easy to understand and made me feel comfortable asking questions. He's patient, encouraging, and genuinely cares about helping you improve. Since starting here, my body has changed so much, but honestly, so has my mindset. I've gained confidence, learned proper form, and actually look forward to coming to the gym. No matter what fitness level you're at, I've never felt judged or out of place. There are people at every stage of their fitness journey, and it's a really supportive environment. I've also attended one of their women's events, which was such a fun way to meet people and be part of the community. It really feels like more than just a gym. If you've been nervous about joining a gym like I was, this is your sign. I'm so glad I took the chance.

The place is spacious compared to other workout studios I've been to in the area. The format is mainly 5 stations with an A & B exercise. You can start at any of the 5 stations & you'll do sets of the A workout followed by the B workout or vice versa. Monday/Wednesday is upper body Tuesday is lower body Thursday is glutes and abs Friday through the weekend is full body (this location isn't open Sunday so you'll have to hit up their other location) We've been going to the evening classes which are taught by Meghan. Who I'd say is one of our favorite instructors (we've been to two other instructor's classes). She's good with explaining and keeping time. She's also a good balance of being a cheerleader/"woo girl" or coming over when you're butchering the exercise! Be prepared to say hello & give your workout buddies high fives!

Marisa was a great, attentive, hands on and a thorough instructor with clear direction.

Studio is clean with dim to dark neon lighting. I had bright yellow socks but appeared pure true white in the studio. Not too harsh where it interfered with the workout. If anything it helps, it feels less sensory overwhelming. Cubbies are inside and in view of, which is great since the instructor also runs the front desk.

Not to mention it's located in the most convenient plaza with a smoothie shop, a target, poke Hawaiian restaurant, organic foods restaurant, ramen, cafe rio etc. Lots of healthy options to choose from after a good workout!

They have all the equipment you could need to work every part of the body. The trainers genuinely care and personalize the program to your needs. Plenty of parking. Lockers are available with a code. It's a get-in, workout, get-out gym. There are no people, just hugging machines or standing around. Everyone is usually doing something, and so it motivates me to keep working out. It's never so busy that it gets uncomfortable. I have seen people of all ages, body types, and abilities here. It is a good mix of healthy people. Cons: No showers yet (they are expanding to include showers and a sauna soon) Only two restrooms. (I have never had to wait to use one, but you never know). Overall, this gym is pretty well organized. They offer plenty of trainers of all genders. I believe they also do rehab and physical therapy. There also is someone that comes to do massages. Everyone I have seen here is pretty friendly and polite. I have been training with Laura, and in the past three weeks, she took me from 0 pull-ups to 20 chin-ups, 1:20 plank to 3:30, and 15 push-ups to 42 in 2mins, and my strength overall has increased.
